VENT FOR CASKS.

SPECIFICATION forming` part of Letters Patent No. 244,396, dated July19, 1881. Application mea May es, 1881. (Moda.)

My invention relates to an air-vent for fer-V mented liquors, which canbe applied either to the bung or to the body of the cask.

My invention further relates to a vent which is of simple construction,easily applied, and which embodies in a single device separable partswhich admit of connection and adjustment for its application to the bungof a cask, or to the staves or head of the same.

Figure l is a vertical section of a bung inserted in a section of acask, with an axial section of my improved vent applied thereto. Fig. 2shows a section of the stave and head of a cash, with another portionadded to the vent-pipe, which is also shown in axial section. Fig. 3shows two views of a vent-pipe used with bungs, as shown in Fig. 1,without the end cap. Fig. 4is an end view of the cap. Fig. 5 is avertical section of the same (enlarged) with the ball therein.

The object of my invention is to produce a vent for casks containingfermented liquors, which can be made cheap, which can easily be removedand cleansed, is not liable to get out ot order, and which can beapplied to either the bung or the body of the cask.

A is the bung. B' is the section of a beercask; B, the vent, consistingof an elbow-pipe, a, and a cap, c, which is screwed upon the end whichturns downward. u' is a hole in the middle of the bung, communicatingwith the interior of the cask through the vent-pipe. The sections of thevent-pipe are threaded, to make them t snugly together gas-tight. Oneend of the pipe screws into the hole a' in the bung, and the other end,which is formed into an elbow, is also threaded to receive the end capc. A plain hole extends through the pipesection a, which is free, exceptat the outer end of the elbow, as seen in the view of the end d, Fig. 3,where a bar, c, is seen across the hole. The object of this bar is toprevent the ball t in the chamber e of cap c from escaping into the parta when the latter is in verted, or when the air-current carries the ballaway from its seat over the hole e. In whatever position the vent isapplied the cap c must be in a vertical position, as shown in Figs. 1,2, and 5, the latter of which shows the normal position of the ball.

Fig. 2 shows the vent applied through the' stave S of a cask, a holebeing first bored through the same and the end of the long arm screwedtherein. In this vent there are three sections-pipe a, which is placedvertically; b, another elbowasection, which is screwed on the horizontalshort limb a" of a, and the cap c. In case the user should desire toapply this vent to the bung A, the interposed middle section, b, istaken oil', the cap c screwed upon the end of a, and the vent applied asseen in Fig. 1. The bung. can be first driven and plugged, or thev ventfirst inserted, as the parts are not liable, from the shock of driving,to get out of place. The bar c is made in the outer end of both sectionsa and b, so that the ball t cannot escape from the inverted conicalchamber e in the cap c. Both the cap c and the section b are providedwith an interior threaded end, to adapt them to t upon the limb a ofpipe-section a. The size of the ball t' (see Fig. 5) is very small inproportion to the chamber c of the cap and the diameter of the pipe. Thehole e is also very small, being but about one-sixteenth of an inch indiameter in the full-sized vent. A No. 8 bird-shot is used for the ball.

The operation of my improved vent is very easily understood. As the gasis drawn oli" .from the beer the air enters the vent through the smallhole e' and sends the ball spinning around the chamber e, finallysettling over the hole e' in the apex ofthe-chamber after suliicient airis admitted through the vent.

am aware that vents have been constructed with air-chambers, valves,&c.; but I do not claim them, as their construction entails heavy costand their adaptability is limited.

In nearly all beer-vents their complex arrangements and cost preventtheir common use. In my device I have adoptedlthe most simple means atthe least cost.

I claim as my invention- 1. In a vent for casks containing fermented IOOliquors, the combination, With an elbow pipen liquor, consisting of theelbow-pipe a with the section, of a screw-threaded cap fitted thereto,bar c', the screw-threaded cap c, and asmall 1o and having an interiorinverted conical chaniball or shot, e', substantially as set forth. berternflinatinqP in a fine hole and containincr T 5 a small ball ori-shot,whereby the passage o?? JOHAb LUGER air is regulated in passing throughsaid vent, Attest: substantially as described. R. A. PIERCE,
